A cover letter should say why you want this specific role, show two or three pieces of evidence that you can do it, and add context the resume cannot, such as a career change, a relocation or what draws you to the employer. It should not repeat your resume line by line. Aim for about 250 to 350 words, in three or four short paragraphs, written in plain language to a real reader.
Think of it as a short argument. Your resume lists facts. Your letter connects those facts to this job and explains the parts that do not fit neatly. If it could be sent to any employer unchanged, it is not doing that work.
What a cover letter is for
A cover letter can do four useful things:
- Show fit. Link your experience to specific needs in the post.
- Add context. Explain a pivot, relocation, gap or unusual background in a sentence or two.
- Show interest. Say why this role or employer, with specifics that are true.
- Show how you write. For jobs that involve writing or relationships, the letter is itself a work sample.
It is not a place to retell your life story, list every skill or apologize for gaps. Whether to send one at all depends on the situation, covered in when a cover letter is worth writing.
The four-paragraph structure
Paragraph 1: the role and the hook
Name the job and give a reason you fit or are interested, in a sentence or two. Skip “I am writing to apply for…” filler.
Weak: “I am writing to express my interest in the Office Manager position at your company.”
Better: “I am applying for the office manager role. I have spent four years running day-to-day operations for a 25-person firm, and your posting’s focus on vendor coordination and onboarding matches the work I do best.”
If someone referred you, mention it here, with their permission.
Paragraph 2: evidence of fit
Pick two or three accomplishments that match the top requirements in the post and tell them briefly, with specifics.
“At my current firm I manage relationships with 15 vendors and negotiated a new office supply contract that lowered our monthly spend. I also built the onboarding checklist now used for every new hire, which cut first-week setup questions.”
Notice scale, an action and a result. The figures are illustrative; use only facts you can support. Choose items that are not simply your top resume bullets, and add a layer the bullet cannot, such as how you approached the problem or why you did it.
Paragraph 3: why this employer or role
This is where many letters turn generic. Give one true, specific reason you want this job, drawn from the post or public information about the organization, such as its customers, its approach or the nature of the work.
“I am drawn to the role because your team supports small business clients directly, which is the type of customer-facing operations work I find most satisfying.”
Avoid flattery (“a leader in the industry”) and unsupported claims (“I have always admired your company”). If you cannot say something specific, shorten this paragraph or fold it into the first.
Paragraph 4: the close
Restate interest and invite the next step in two sentences. “I would welcome the chance to discuss how my experience could support your team. Thank you for your time.”
Letter versus resume
| Content | Resume | Cover letter |
|---|---|---|
| Job titles, dates, employers | Yes | Only if needed |
| Every duty and skill | Yes | No |
| Two or three key stories | Short bullets | Brief narrative with context |
| Reason for applying | No | Yes |
| Explanation of a pivot or gap | Short line at most | A sentence or two |
| Tools and certifications | Yes | Only if central |
The letter should feel like the same person as the resume but add something new. Its story should match the one in your resume summary.
A sample letter
This is a fictional example. Replace every detail with your own accurate information.
Dear Ms. Alvarez,
I am applying for the customer operations specialist role. For the past three years I have handled order issues and vendor communication for an online retailer, and the combination of customer contact and process improvement in your posting is exactly the work I want to do more of.
In my current job I answer about 40 customer tickets a day and coordinate with two fulfillment partners to resolve delays. After noticing that many tickets came from the same three shipping problems, I created a short reference guide for the team and a template for notifying customers early. I also train new team members on our ticketing tool.
I am particularly interested in this role because it combines direct customer support with the chance to improve the processes behind the problems, which is the part of my job I enjoy most. Your posting mentions reporting on recurring issues, and I have built monthly summaries for my manager using spreadsheet pivot tables.
I would welcome the chance to talk about how I could contribute to your team. Thank you for your time.
Sincerely, [Your name]
At about 190 words it is concise, specific and tied to the post. The details are invented.
Tone and style
- Write like a competent person talking to another one. Not stiff, not chatty.
- Use “I” naturally, but do not start every sentence with it.
- Be specific and modest. Show results through details, not adjectives.
- Use the employer’s vocabulary when accurate.
- Avoid cliches such as “team player,” “passionate,” “think outside the box” and “hit the ground running.”
- Keep it to one page, often half a page.
- Address a person if you can find a name in the post or on the organization’s public pages. If not, “Dear Hiring Team” is acceptable.
Common mistakes
- Repeating the resume. If every sentence appears there, cut it.
- A long self-introduction at the start.
- Focusing on what you want instead of what you can offer.
- Apologizing for missing requirements. State what you have, not what you lack.
- Using the same letter for every job. At minimum change the role name, the opening and the fit paragraph.
- Typos and a wrong company name, which cost credibility quickly.
- Raising salary or schedule demands unless the application asks.
If you lack some requirements, emphasize related experience calmly. For an unusual background, read how to write a cover letter for a career change.
A 30-minute drafting routine
- Highlight the top three requirements in the post (4 minutes).
- Note one accomplishment per requirement, with specifics (8 minutes).
- Write one honest sentence on why this role or employer (3 minutes).
- Draft the four paragraphs in plain language (10 minutes).
- Cut to under 350 words, check names and proofread aloud (5 minutes).
Save a base version with placeholders so later letters take about 15 minutes. Before sending, underline every sentence that could move into a different application unchanged. If most of the letter is underlined, rewrite the fit paragraph around something specific from the post. A half-length but fully specific letter is usually stronger than a long, boilerplate one.
Where this comes from
This guide is based on cover-letter advice published by university career centers and on common job-search practice. Published surveys of how recruiters use cover letters come mostly from commercial sources and conflict with one another, so no claim is made here about how often letters are read. The sample letter and all figures are invented for illustration, and no letter can guarantee an interview. Prices, rates and limits change, so anything time-sensitive should be checked at the source.
